RAIL FASTENING, JOINT, 8C.

SPECIFICATION forming part of Letters Patent No. 443,309, dated December 23, 1890.

Application tiled September 9, 1890. Serial No. 364,426. (No model.)

To all whom it may concern,.-

Be it known that I, FRANK BACK, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Rail Fastenings, Joints, tbc., which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in rail-fastenings; and it consists of the combinat-ion of parts hereinafter set forth.

Figure l represents a perspective View of a rail-joint embodying my invention. -F-ig. 2 represents a view of a transverse section on line 0c Fig. l. Fig. 3 represents a viewof a transverse section on line y y, Fig. 1. Fig. 4 represents a modification, and Fig. 5 represents a transverse section thereof on line e', Fig. 4c.

Similar letters of reference indicate corresponding parts in the several Iigu res.

Referring to the drawings, A A designate sections of a rail, and B B ish-plates on the sides of the Web thereof. One of the said plates B is formed with bent portions Vor lips O at its ends, and the plates and Web of the rail have openings to receive the non-rotatable bolts D, which are passed through the same and have on their screw-threaded ends the nuts E for tightly binding the parts together.

F designates a locking-bar, having,` recesses G in one of its sides so as to tit on the sides of the nuts and prevent them from being rotated on the bolts. In one side of the locking-bar are openings l-l, adapted to receive the pins J of the springs K, which latter are fastened to the iish-plate B, thus preventing an upward movement of the locking-bar, the lips of the fish-plate providing` against any longitudinal motion of the same.

In the modification a fish-plate without the bent ends or lips is employed, and toprevent its movement it is provided With the pins L, which enter openings M in the locking bar F and have the split keys N for holding' them in place. The said openings may be near the ends of the bar, or a single opening near the center thereof may he used, as is shown in Fig. t in dotted lines.

It is evident that the device is applicable to the fastening of all kinds of plates and rails other than those used on railroads.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a rail-fastening'non-rotatable bolts with nuts thereon, a locking-bar with recesses to engage said nuts, and locking-springs for said bar, substantially as described.

2. In a rail-fastening, a plate having lips on its en ds, a locking-bar with recesses on its side, and springs secured to the said plate and having pins adapted to enter openings in the said bar, said parts being combined substantially as described. n

3. In a rail-fastening, non-rotatable bolts with nuts on their ends, a locking-bar with recesses to receive said nuts, and springs With pins adapted to enter said openings in said bar, said parts being combined substantially as described. I

FRANK BACK.
